LC75857E, LC75857W 1/3, 1/4-Duty LCD Driver with Key Input Function Overview The LC75857E and LC75857W are 1/3 duty and 1/4 duty LCD display www.onsemi.com drivers that can directly drive up to 164 segments and can control up to four general-purpose output ports. These products also incorporate a key scan circuit that accepts input from up to 30 keys to reduce printed circuit board wiring. Features Key input function for up to 30 keys (A key scan is performed only when a key is pressed.) 1/3 duty and 1/4 duty drive schemes can be controlled from serial data. 1/2 bias and 1/3 bias drive schemes can be controlled from serial data. PQFP64 14x14 / QIP64E Capable of driving up to 126 segments using 1/3 duty and up to 164 LC75857E segments using 1/4 duty. Sleep mode and all segments off functions that are controlled from serial data. Switching between key scan output and segment output can be controlled from the serial data. The key scan operation enabled/disabled state can be controlled from the serial data. SPQFP64 10x10 / SQFP64 Switching between segment output port and general-purpose output port LC75857W can be controlled from serial data. The common and segment output waveform frame frequency can be controlled from the serial data. Switching between RC oscillator mode and external clock mode can be controlled from the serial data. Serial data I/O supports CCB* format communication with the system controller. Direct display of display data without the use of a decoder provides high generality. Independent VLCD for the LCD driver block. (When the logic block supply voltage VDD is in the range 3.6 to 6.0 V, VLCD can be set to a voltage in the range 0.75 VDD to 6.0 V, and when VDD is in the range 2.7 to 3.6 V, VLCD can be set to a voltage in the range 2.7 to 6.0 V.) Provision of an on-chip voltage-detection type reset circuit prevents incorrect displays. * Computer Control Bus (CCB) is an ON Semiconductors original bus format and the bus addresses are controlled by ON Semiconductor.
